Wow Reinaldo I think you should write a book. Lots of good info right there.
I have to agree with Dr Joe. The cutoff date should not be moved. If it did as stated everyone would be chasing the newest platform to give them that minute edge they think they might have. it would be no different then what most do with there current vehicles.
I do think that maybe certain models should be allowed as Reinaldo pointed out with the YZ10 lineup. I personally would like to see the XX-4 allowed.
